Did you know?
Webb21 maj 2015 · Apoplast creates a main pathway called apoplastic pathway or apoplasty that helps to transport water and ions from the soil through root to xylem elements. In the plants with secondary growth, the major portion of water is transported by apoplasty in the root cortex as cortical cells are loosely packed and have low resistance to the water flow. Webb1 juni 2024 · Apoplastic phloem loading is an energy dependent process In this the photoassimilates are first transported from the mesophyll cells via bundle sheath cells to the extracellular apoplastic region The loading of sucrose from apoplast to sieve element-companion cell complex requires a Sucrose- H+ Symporter (secondary active …
Webb7 apr. 2024 · Phloem sap transport is essential for plant nutrition and development since it mediates redistribution of nutrients, metabolites and signaling molecules. However, its biochemical composition is not so well-known because phloem sap sampling is difficult and does not always allow extensive chemical analysis.

This translocation occurs via the plasma membrane of the sieve tubes, which are composed of a series of connected sieve elements. The mechanism of the longitudinal assimilate movement in sieve tubes has been explained by two different models of phloem loading: 1. Symplastic loading, 2.

Apoplasmic loading is associated to the activity of membrane transporters whereas symplasmic loading relies on transport across plasmodesmata.
